  • STA-30, a new member of the SWY family of molecular sieves, methods of preparation and use
    Patent number: 11879374
    Abstract: The present invention is directed to a method of preparing a molecular sieve of SWY framework type, denominated STA-30. STA-30 is synthesized using 1,4-diazabicyclo[2.2.2]octane, 1-azabicyclo[2.2.2]octane derivates and combinations thereof as structure directing agents. The resulting molecular sieve is useful as catalysts, particularly when used in combination with exchanged transition metal(s) for the Selective Catalytic Reduction (SCR) of NO.

  • STA-20, a novel molecular sieve framework type, methods of preparation and use
    Patent number: 10213776
    Abstract: STA-20, a molecular sieve having a new framework type, is described. STA-20AP (as prepared) can have an alkyl amine, such as trimethylamine, and 1,6-(1,4-diazabicyclo[2.2.2]octane) hexyl cations (from diDABCO-C6) as SDAs. A lower alkyl ammonium hydroxide, such as tetrabutylammonium hydroxide, can be used as a pH modifier for making SAPO STA-20. A calcined product, STA-20C, formed from as made STA-20 is also described. Methods of preparing STA-20, activating STA-20 by calcination, and metal containing calcined counterparts of STA-20 are described along with methods of using STA-20 and metal containing calcined counterparts of STA-20 in a variety of processes, such as treating exhaust gases and converting methanol to olefins are described.
